T0 f//ZZ 11177/0711/ it mfr/7j concern:

Be it known that l, CHARLES A. GLOVER, a citizen of the United States, and a resident of Bellport, in the cointy of Sziilolk and State of New York, have invented a new and linproved Oil-Shell, of which the following is a full, clear, and exact description.

The prfrpose of the invention is to provide a shell adapted to contain oil and to be fired 'l rom a cannon or iportar over a body of water to distribute oil thereupon at a point distant from the shore and to' so construct the shell that during the major portion of its Hight the outlet for the oil will be closed but automatically opened at or about the tirre the shell strikes the water, thereby permitting the oil to spread. upon the rough eleirY ent and quiet the saute.

The invention consists in the novel construction and combination ot the several parts, as will be hereinafter hilly set forth, and pointed out in the claims.

Reference is to be had to the accoirpanying drawings, forir ing a part of this specification7 in which similar characters ol' reference indicate corresponding parts in all the iigures.

Figure 1 is a longitudinal section through the shell, illustrating its parts in the position they occpy when the shell is not in use. Fig. 2 is a section similar to Fig. 1, illustrating the position the shell assumes in flight and the position of the parts at such time. Fig. 3 is a longitudinal vertical section of the shell, illustratingthe position of the parts when the shell has entered the water; and Fig. 4 is a rear end view oi the shell with the parts in the position shown in Fig. 3.

A represents a tubular body, which is preferably ot consistent diarn eter throughout, and the outer end of said body is closed by a weighted tip or plug 19, having an internal collar 1.0a to lit the bore of a gun, while the opposite or inner end of said body is closed by a slip-cap 11, normally held in place by a bayonet-slot connection 11'L and which is usually provided with a spring 12 upon its inner face adapted to bear against a stopper 13, preferably n: ade of' cork, which stopper also tends to close the inner end of the body A and prevents the exit of iiuid contained in the body when the cap 11 is removed. T he stopper 13, which is a iiat disk, is made to fit against a flange 14a, extending outward from a diaphragm 14, which diaphragm, as

l illustrated particularly in Fig. 4, is provided, preferably, with aperturesY 15. The apertures in the diaphragm 14 are normally closed by meansk of a valve B, mounted to slide in the body A between its ends. This valve consists of an outer or closing disk 16, an inner perforated disk 16, and a connecting-tube 16h, together with a steni17,which passes through both disks, being secured to the inner one. The stein l17 also passes through the connecting-tube 1Gb and loosely throi: gh the diaphragm 14, having a nut 18 at its outer end. The valve-stein 17 is also provided with an annular recess 17 near its outer end, which is at the opening in the diaphragm 14 when the valve is opened, as Vshown in Fig. 3, serving to hold the valve in such position while the oil is discharging from the missile.

A ball 19 is located within the bodyA, being free to travel from the tip or plug 10 to the valve 16, and when said ball 19 engages with the valve 16 it closes said valve,

In the further construction of the body A iins 2() are exteriorly secured thereto at its inner end, as is particularly shown in Fig. 4, and while these fins are shown as iour in number they in ay be inore or less as required. The iins 2() at their outer edges are inade to taper troni their rear ends inward toward the body A g but while such shape of the iins is preferred other lorins may be employed.

In operation the shell is iilled with oil, as is illustrated in Figs. 1 and 2, and then the outer or weighted end of the shell is introduced into the cannon, the forward ends of the fins bearing against the muzzle. Vllhen the cannon is fired, the shell reverses and assumes the position shown in Fig. 2, due sonnewhat to the ins, which fins tend to guide said shell through the air, steadying it to some extent and tending to prevent its revolving too rapidly. It inay here be stated that when the shell is introduced into the cannon the slip-cap 11 is removed.

i As the shell leaves the cannon, assuming the upward inclination shown in Fig. 2, the ball 19 rolls to the innner end of the body A and forces the valve 16 to a seat upon the diaphragm 14, thus causing the stein 17 of the valve to strike the sto )per 13 and force it out from the body, as is also shown in Fig. 2. As the shell descends and enters the water the ball rolls again to the tip or outer end of IOO IOS

the body A, as is shown in Fig. 3, and the water will then force the valve 16 inward, uncovering the opening l5 in the diaphragm 14 and permitting the oil in the body A to escape therefrom and flow upon the water.

This shell is exceedingly eiective in practice, it is simple and reliable, and is practi.

cally automatic in action.

Having thus described my invention, l claim as new and desire to secure by Letters vP atentthe shell.

3. A shell consisting of a tubular body provided. with a weight at its forward end, a

removable stopper at its inner end, an apertured diaphragm located opposite the inner face of the stopper, a valve for said diaphragm, the stem of which valve is adapted ier engagement with said stopper, and a `movable object within the body, adapted to seat the valve and cause its stem to force the stopper out at one position of said shell.

4. A shell consisting of a tubular body provided with a weight atlits Jforward end, a removable stopper at its inner end, an apertured dia hragm located opposite the inner -face of t e stopper, a valve for said diaphragm, the stem of which valve is adapted for engagement with said stopper, a movable object within the body, adapted to seat the vvalve and cause its stem to force the stopper out at one position of said shell, and fins exteriorly located at the inner end portion of the body of the shell.

5. A shell consisting of a tubular body, a weight at the outer end of said body, a stopper removably placed within the inner end of the stopper and normally closing said inner end, an apertured diaphragm secured within the body opposite the inner face of said stopper, a valve adapted to close the apertures in the diaphragm, a stem extending from the valve through said diaphragm, adapted when the valve is seated to engage with and dislodge said stopper, a movable weight located within said body, adapted to travel from end to end thereof and when at the inner end oi' the body to seat said valve, and fins exteriorly located at the inner end portion of the body. A

6. A shell consisting of a tubular body, a weight at the outer end of said body, a stopper removably placed within the inner end of the stopper and normally closing said inner end, an apertured diaphragm secured within the body opposite the inner face of said stopper, a valve adapted to close the apertures in thediaphragm, a stem extending Jfrom said valve through said diaphragm, adapted when the valve is seated to engage with and dislodge said stopper, a movable weight located withinsaid body, ada ted to travel from end to end thereof and w en at the inner end of the body to seat said valve, fins exteriorly located at the inner end portion of the body.

va slip-cap for the inner end of the body, and

a spring-cushion located between said springcap and the said stopper.

In testimony whereof I have signed my name to this specification in the presence et two subscribing witnesses.
